At the investigation phase we focus on refining and better understanding the potential risks so that they can be quantified and accounted for. This makes the rest of the development process quicker, safer and easier to budget for.
Our ground investigations are tailored to provide the information that’s needed based on what we expect the ground conditions to be, and what the proposals are.
A Phase 2 Ground Investigation is a more detailed, intrusive investigation that follows a Phase 1 Desk Study. It aims to confirm and quantify potential ground risks identified in the initial assessment. This involves on-site investigations, such as boreholes, trial pits, and soil and groundwater sampling, to gather detailed information about ground conditions. The Phase 2 site investigation analyses soil strength, contamination levels, and groundwater characteristics, providing data crucial for foundation design, remediation planning, and risk assessment. It's essential for ensuring the safety and stability of a development, and addressing potential environmental liabilities.
A Coal and Shallow Mining Investigation is a detailed on-site assessment that follows a desk-based review of potential mining risks. It aims to physically verify and quantify hazards associated with past coal and shallow mining activities. This investigation involves techniques like borehole drilling, geophysical surveys, and mine shaft inspections to gather subsurface data. The Coal and Shallow Mining investigation determines the exact location and condition of mine workings, assesses the potential for subsidence, and measures the presence of hazardous gases. This intrusive investigation is crucial for confirming the risks identified in preliminary studies, enabling the design of appropriate mitigation measures, and ensuring the safety and stability of proposed developments in former mining areas.
A soakaway investigation is a detailed on-site assessment to determine the suitability of a location for a soakaway drainage system. It goes beyond initial assessments by performing practical tests to verify ground permeability. This typically involves digging trial pits and conducting percolation tests, which measure how quickly water infiltrates the soil. The investigation also considers groundwater levels and potential obstructions. This practical, on-site investigation provides precise data for designing an effective soakaway system, ensuring proper surface water drainage and minimising the risk of flooding or waterlogging.
